Networking for Systems Administrators (IT Mastery)

Stop waiting for the network team! 
If basic TCP/IP was hard, network administrators couldn't do it. Servers give sysadmins a incredible visibility into the network--once they know how to unlock it. Most sysadmins don't need to understand window scaling, or the differences between IPv4 and IPv6 echo requests, or other intricacies of the TCP/IP protocols. You need only enough to deploy your own applications and get easy support from the network team.This book teaches you: 

• How modern networks really work 
• The essentials of TCP/IP 
• The next-generation protocol, IPv6 
• The right tools to diagnose network problems, and how to use them 
• Troubleshooting everything from the physical wire to DNS 
• How to see the traffic you send and receive 
• Connectivity testing 
• How to communicate with your network team to quickly resolve problems 

A systems administrator doesn't need to know the innards of TCP/IP, but knowing enough to diagnose your own network issues transforms a good sysadmin into a great one.
